How to choose microneedles suitable for different skin positions?

Choosing microneedles suitable for different skin conditions requires comprehensive consideration of skin thickness, problem type, tolerance, as well as microneedle type and parameters. The following are some specific suggestions：

Selection of microneedles for different skin thickness regions

For areas with thin and tender skin, such as around the eyes, orbit, neck, etc., short microneedles should be selected, generally around 0.5mm-1.0mm, and relatively low clinical energy parameters are recommended. Because the skin in these areas is more sensitive, shorter needle lengths can reduce damage and irritation to the skin, while also achieving certain therapeutic effects.

For areas with thicker skin, such as cheeks, abdomen, etc., the needle length can be appropriately increased, generally between 1.0mm-2.5mm. A longer needle length can stimulate the skin more deeply, promote collagen production, and improve problems such as skin sagging and wrinkles.

Micro needle selection for different skin problems

Anti aging and wrinkle removal: For skin with aging problems such as wrinkles and sagging, radiofrequency microneedles such as gold microneedles can be chosen. It combines microneedles and radiofrequency energy to stimulate collagen regeneration and improve skin elasticity. For example, brands such as Peninsula Gold Micro Needle and Luchuangli Gold Micro Needle are suitable for anti-aging because their energy is more concentrated and can act deep into the skin.

Acne and scar repair: For acne and acne scars, microneedle therapy can promote scar repair and improvement by stimulating the skin's self repair mechanism. At the same time, microneedles can also be used in combination with cosmetic therapy to directly introduce drugs into the skin, achieving better therapeutic effects. For example, gold microneedles can be used to remove acne scars. Its unipolar and bipolar radiofrequency combined with insulated microneedle technology generates a thermal effect through radiofrequency, stimulating the regeneration of skin collagen and improving acne scars.

Sensitive skin: Mild and less irritating microneedles, such as nanomicroneedles, should be selected for sensitive skin. The micro pores formed by nano microneedles are small, causing minimal damage to the skin and quick recovery, making them suitable for use on sensitive skin. In addition, during the stable period, sensitive muscles do not have obvious symptoms of itching, stabbing pain, or tightness. Only mild redness can be treated with gold radiofrequency microneedle therapy, as it can rebuild skin microcirculation and dermal capillaries. By using radiofrequency energy and a three-dimensional lattice, it can repair the skin barrier and improve sensitivity.

Pigmentation issues such as melasma: Microneedle therapy can improve the activity of epidermal cells, promote melanin metabolism, and help repair skin barrier function through micro damage, thereby improving problems such as melasma.

Characteristics and applicability of different types of microneedles

Roller microneedles: The most widely used are generally composed of a handle and a roller, with several rows of microneedles distributed on the roller, with a length generally ranging from 0.5 to 3mm. They are suitable for multiple uses on a large area of skin and can be used to treat acne, acne scars, pits, wrinkles, thin and sensitive skin stratum corneum, skin aging, sagging, obesity lines, and stretch marks.

Seal microneedle: composed of a handle and a seal shaped head, the microneedle is located on top of the seal and acts vertically on the skin during use. It is generally used for local scar treatment.

Electric microneedle: This type of microneedle is divided into a pen like body and a vibrating stamp microneedle head. Through mechanical drive, the microneedle at the head can vibrate repeatedly, eliminating the disadvantage of uneven skin stress when the operator uses the microneedle.

Radiofrequency microneedle system: By using microneedles to deliver electrical energy subcutaneously, it can treat scars, hyperhidrosis, skin tightening, facial rejuvenation, and other conditions without damaging the epidermis. For example, the Golden Microneedle is a radiofrequency microneedle system that is suitable for improving issues such as enlarged pores, dull skin tone, acne, or scars.

Dissolved microneedle: made by mixing soluble biomaterials with drugs or active ingredients, the needle gradually dissolves after piercing the skin, and the drug is slowly released. It is suitable for treatments that require long-term effects.

Hollow microneedle: Directly delivers drugs to specific skin target layers through internal micro pores, suitable for treatments that require precise dose control.

precautions

Skin condition assessment: Before using microneedles, ensure that the skin is not damaged, inflamed, eczema, or in a sensitive period.

Choose legitimate institutions and certified doctors: In order to ensure the safety and effectiveness of treatment, it is necessary to choose institutions and certified doctors authorized by the manufacturer for operation. Certified doctors can customize energy and needle insertion depth based on your skin condition, skin tolerance, and other factors.
